Abstract :
In this work, Symbol Error Probability (SEP) and Outage Probability (OP) expressions for 2×1 and 2×2 Alamouti Space-Time coded Orthogonal Frequency Division Multiplexing (OFDM) signals over Nakagami-m fading channels are derived and validated by simulations. First, the probability density functions (PDF) at the output of antennas are derived, then their moment generating functions are taken to obtain the SEP expressions. Besides, the OP expressions are derived by using the PDFs. The numerical results obtained from the derived expressions of the SEP and the OP and the simulation results are completely match, hence validate the derivations.
